Default Anyone know this crossover calculator?

Anyone hear of - or better yet, try - this crossover component calculator? Wonder if it looks plausible and what kind of results to expect? Rather than springing right away for an active setup thinking I will try a passive 4th order Butterworth or L-R. Will be doing a front screen array of three two-ways incorporating a single 2226j woof and 2446h comp driver and 2385a horn. Thinking of crossing at 600 Hz.

any other thoughts, advice, schematics also more than welcome! I have made a lot of sawdust, but this is my first foray into solder fumes.

I compared it to Erse, and for a LR24 they return exact same values EXCEPT one inductor in the tweeter is double the value.
Do I need a third calculator to break the tie?
Even with an L-pad I wouldn't have the range to make it up if I use the 'wrong' one. What would be the sonic effect of it being either too large or too small a value? This is the inductor closest to the driver.

I'm not that smart but from reading about crossovers electronic is the way to go if you have the amps. Designing and getting a 4th order to work in the real world is expensive.
